ighlights of key new features in PSIM Version 9.3 are: • New Motor Control Design Suite • Improved HEV Design Suite • New F2803x Target for support of TI F2803x series fixed-point DSP • Support of TI Digital Motor Control Library • MTPA and Field Weakening control blocks for induction motor and nonlinear PMSM • EMI standards in Simview Description of key new features in Version 9.3, as compared to Version 9.2, is given below. • Motor Control Design Suite The all new Motor Control Design Suite provides the total solution for motor drive system design. From system specifications, the Motor Control Design Suite automatically designs all the controllers with proper stability margins, and generates a complete system that is operational and ready to simulate. Three design templates are provided in the Motor Control Design Suite: linear and nonlinear PMSM drive with maximum-torque-per-ampere control and field weakening control, and induction motor drive with vector control and field weakening control. The figure below on the left show the Design Suite interface of a nonlinear PMSM drive system, and the figure on the right shows the complete system schematic. In addition, using the auto code generation capability in PSIM, one can generate the control code automatically for DSP implementation, making it possible to go from design to implementation and hardware implementation in one easy step.

In this release, the Design Suite also support nonlinear PMSM. In a nonlinear PMSM, inductances and back EMF constant are a function of the motor current. Designing controllers HEV powertrain systems using nonlinear PMSM is a very challenging task, and such task is made considerably easier with the HEV Design Suite. The figures below show the Design Suite interface of series/parallel HEV and Plug-in HEV (PHEV) powertrain systems with nonlinear PMSM. • F2803x Hardware Target Through the new F2803x Hardware Target, PSIM now supports TI F2803x series fixed-point DSP. Basic DSP functional blocks are provided, includi ng PWM generators, A/D converter, digital input and output, encoder, capture, etc. A list of the F2803x Target library elements is shows below: Series/Parallel HEV Plug-In HEV New Features in PSIM Version 9.3 Page 3 www.powersimtech.com These elements can be used in regular simulation as well as automatic code generation. The generated code is ready to run on the target DSP. In fixed-point calculation, the selection of fixed-poi nt positions is an important issue. If the fixed- point range is too low, the variable value may overf low. But if the fixed-point range is too high, the calculation resolution will suffer. To address this problem, PSIM provides the function to check the fixed-point range based on simulation results, and give indication if a particular output is close to overflow or already overflow, or is too c onservative in the fixed-point position setting. For example, the figure below shows the range check result of a circuit. It indicates that some variables are close to overflow (highlighted in ye llow), and some already overflow (highlighted in red). • TI Digital Motor Control Library TI provides the Digital Motor Control (DMC) Library to facilitate the coding for digital power and motor drive applications. This library is now supported in PSIM. The figure below shows a list of the TI DMC Library elements.
